Reproductive Performance of Female Antarctic Fur Seals: The Influence of Age, Breeding Experience, Environmental Variation and Individual Quality
Read more of: Reproductive Performance of Female Antarctic Fur Seals: The Influence of Age, Breeding Experience, Environmental Variation and Individual Quality1. The reproductive performance of female Antarctic fur seals was examined in relation to age, reproductive experience and environmental variation over 10 consecutive years (1983-92) at Bird Island, South Georgia. […]

Interhemispheric asymmetry of the high-latitude ionospheric convection pattern
Read more of: Interhemispheric asymmetry of the high-latitude ionospheric convection patternThe assimilative mapping of ionospheric electrodynamics technique has been used to derive the large-scale high-latitude ionospheric convection patterns simultaneously in both northern and southern hemispheres during the period of January […]

Improvements to the accuracy of measurements of NO2 by zenith-sky visible spectrometers
Read more of: Improvements to the accuracy of measurements of NO2 by zenith-sky visible spectrometersVisible spectra of the zenith-sky were recorded at Faraday in Antartica during 1990. Line-of-sight NO2 amounts were deduced by fitting laboratory cross-sections to the spectra. A new procedure was used […]

Central volcanoes as sources for the Antarctic Peninsula Volcanic Group
Read more of: Central volcanoes as sources for the Antarctic Peninsula Volcanic GroupFrom at least the Early Jurassic to the Miocene, eastward subduction of oceanic crust took place beneath the Antarctic Peninsula. Magmatism associated with the subduction generated a N-S linear belt […]

The annual cycle of planktonic ciliates in nearshore waters at Signy Island, Antarctica
Read more of: The annual cycle of planktonic ciliates in nearshore waters at Signy Island, AntarcticaThe abundance and biomass of marine planktonic ciliates in Borge Bay, Signy Island, were determined at monthly intervals between April 1990 and June 1991. At least 24 different ciliate taxa […]
